Built on a solid foundation, the Pro 800 has a one-piece steel fram and is housed fully in mirror finished AISI 304 stainless steel. With a set of high quality steel legs, the Profitec Pro 800 towers over your countertop in case you decide to plumb the drain or water line. The removable cup warmer is passively heated by the excess heat coming from the boiler. The tray can hold 6 espresso cups and comes off for access to the water reservoir. With the large 3.5 liter (118oz) copper boiler you have the capability for endless water while pulling shots. With the PID you can monitor the temperature inside of the boiler and adjust the brew temperatures to help get you that perfect extraction.
